The blow-through floor was simply the result of a mistake. It had nothing to do with increasing the width of he building on a few of the floors.
The team published this nonsense to try to cover up their huge mistake. The design did change to reduce the changes in SF in the floors, but that was a direct result of the shit show the condo floor plans are even now... it's not easy to design the same floor plan for a unit that changes 3 to 4 feet across its entire exterior walls without some very awkward and bizarre consequences...
the developer did not force an increase in some of the condo plans (which did not change bedroom/bath counts at all) only to sacrifice some of the most prime SF in the entire project at the blow through and reduce the number of units to be sold...
the a/e team just realized way too late that the shear strength of the building was inadequate... wouldn't be the first time this has happened with a high profile skyscraper... (google the john hancock building in Boston and the citicorp tower in NYC)
